Abstract (en)

[origin: EP0319659A2] A process for producing a composite laminate comprising a insert part and an injection-molded resin part is disclosed, which comprises coating the insert part with a primer comprising a copolymer aqueous emulsion having a glass transition point of not higher than 20 DEG C which is obtained by emulsion polymerization of a monomer mixture consisting mainly of (a) from 35 to 75% by weight of an alkyl acrylate having from 1 to 8 carbon atoms in the alkyl moiety thereof, (b) from 10 to 50% by weight of an alkyl methacrylate having from 1 to 4 carbon atoms in the alkyl moiety thereof, (c) up to 15% by weight of styrene and/or acrylonitrile, the sum of the (b) and (c) components ranging from 15 to 55% by wieght, (d) up to 5% by weight of a vinyl monomer selected from the group consisting of an alpha , beta -unsaturated acid or an anhydride thereof, 2-hydroxyethyl (meth)acrylate, 2-hydroxypropyl (meth)acrylate, (meth)acrylamide, and methylol(meth)acrylamide, and (e) up to 30% by weight of other vinyl monomer(s), drying the primer, inserting the insert part into a cavity of an injection mold, injecting a molten resin into the cavity to thereby unite the insert part and the injected resin molded part into one body. The composite laminate is resistant to thermal shocks or electrical shocks.
